Problems solved by technology

[0005] In order to make up for the deficiencies of the prior art, it is difficult to ensure that the gauge rod as the fulcrum is subjected to a stable limit on the blackboard when the existing calculus curve modeling drawing tool is used to draw on the blackboard with compass; And when the compass rotates, due to its large size and inconvenient operation, it is easy to cause the angle between the gauge rod as the fulcrum and the blackboard to change, causing the graph to be drawn to be skewed; the present invention proposes an easy-to-use calculus curve construction model drawing tool

Embodiment approach

[0032] As an embodiment of the present invention, the No. 1 suction cup 26 includes a suction cup body 261 and a No. 1 sleeve 262, and the end of the compass leg 21 is embedded in the inner hole of the No. 1 sleeve 262; Two half sets 263 are formed, and the suction cup body 261 is fixedly connected to one of the half sets 263, and the half sets 263 are connected by bolts; the parts of the half sets 263 close to the sides of the compass legs 21 are uniformly provided with fixing blocks 264 , the fixing block 264 is inserted into the annular groove 211 provided at the corresponding position on the side of the compass leg 21 .

[0033] During work, in the drawing process, the No. 1 sucker 26 is fixed on the drawing blackboard 1, and the compass supporting leg 21 on the drawing compasses 2 rotates in the No. 1 cover 262 on the No. 1 sucker 26; The fixing block 264 is embedded in the annular groove 211 on the compass leg 21, so that the compass leg 21 is fixed in the direction perp...

Abstract

The invention belongs to the technical field of drawing tools, in particular to an easy-to-use drawing tool for calculus curve modeling, comprising a drawing blackboard, a drawing compasses and a fixing frame, the drawing blackboard is fixed on the wall by bolts, the The fixed frame is installed on the drawing compasses; the drawing compasses include compasses legs, extension rods, pen caps, connecting sleeves, handles and No. 1 suction cup; the present invention makes the No. 1 suction cup be adsorbed on the drawing blackboard surface, thereby making the compasses legs The end is fixed to prevent the end of the compass leg from sliding during the drawing process; and the fixing sleeve makes the compass leg limited, so as to avoid the change of the angle between the compass leg and the drawing blackboard during the drawing process, thereby avoiding The curve to be drawn is skewed, which affects the accuracy of the calculus curve model, thus affecting the teaching effect.

Description

technical field [0001] The invention belongs to the technical field of drawing tools, in particular to an easy-to-use drawing tool for calculus curve modeling. Background technique [0002] Calculus is a mathematical concept, and it is a branch of mathematics that studies the differentiation and integration of functions and related concepts and applications in advanced mathematics. It is a basic subject of mathematics, and its content mainly includes limits, differential calculus, integral calculus and their applications. Differential calculus includes the calculation of derivatives and is a theory of rates of change. It enables functions, velocities, accelerations, and slopes of curves to be discussed with a common set of notations. Calculus, including the calculation of integrals, provides a general set of methods for defining and calculating areas, volumes, etc. In college classrooms, when teachers teach calculus-related knowledge, they often need to model calculus cur...
